Microsoft's office offerings comes very close (cept for the free part - which i guess is just a bonus and not a requirement). Although i have to say, despite microsoft's attitude for keeping compatibility and old stuff working, they too could chuck a google reader one day, and deprecate/remove a needed service (along with all your data).

What's needed is a syndication of data, and inter-operable apps. Like how xmpp worked. But of course, all vendors don't like this, because it turns themselves into a commodity.
